Compression and heating of indirectly driven spherical fusion targets on the ISKRA-5 facility

The experiments to study the indirect drive targets' dynamics in a highly s ymmetrical X-radiation field were performed on the ISKRA-5 facility. This p aper covered the results of experiments with the targets in the form of a C u spherical hohlraum, the internal surface of which is coated with Au, with six holes for laser radiation input. Tn the center of the aforementioned h ohlraum, a glass capsule filled with D-T gas was placed. In several experim ents, the central capsule was coated with an ablator made of plastic with a different thickness. This allowed us to perform a series of experiments in which the different compression degree of D-T fuel was achieved. The analy ses of experimental results revealed good agreement between the latter and the spherically symmetrical hydrodynamic calculations.
